    Abstract: A cementitious composition comprising a crystalline phase and an amorphous phase, and an activator selected from the group of materials comprising inorganic bases. In some cases the crystalline phase is gehlenite. In some cases the crystalline phase is anorthite. In some cases the amorphous phase is amorphous calcium aluminum silicate. In some cases the activator is elected from OPC (1-70 wt %), free lime (1-20 wt %), calcium hydroxide (1-20 wt %), and alkali hydroxides (NaOH, KOH 1 to 10 wt %), individually or in combination. A low lime cementitious material is cured by reaction with a curing reagent that includes a reagent chemical that is synthesized from CO2. Examples of such a reagent are oxalic acid and tartaric acid.

    Abstract: A method of preparing and rapidly curing a composite material having a thin cross section. The composite material includes a mixture of solid particles, at least some of which are a material that reacts with CO2, such as a silicate, for example Wollastonite. The green material is prepared by mixing the solid components with a liquid such as water to form a slurry, and forming green bodies by placing the slurry in forms. The green bodies are reacted with CO2 to form cured composite materials having thin sections, in the range of 10 to 15 mm. Curing in periods of 6 hours has been demonstrated.
